PP obtained 44.6% of the vote and 186 (53%) MP's, up 4.7 points in votes and 9 points in MP's in relation to 2008. The results basically match (slightly surpassing) those of 2000, when PP had obtained its first absolute majority, but are nonetheless the best results ever for the party. Still, expectations were for an even (slightly) better result. A simple and rough (not taking sample sizes into account) average of the very last polls (those whose fieldwork took place after November 7th) gave PP a 45.9% average. Fernández-i-Marín's more sophisticated approach generated the same average, with an interval between 45% and 46.8%.
PSOE obtained 28.7% of the vote and 110 (31.4% of) MP's, down more than 15 percentage points in votes and 17 points in MP's. It's the party's worst result ever. Although the debacle was predicted, somewhat better was expected. A simple average of the very last polls was 30.6%, Fernández-i-Marín estimated 31.1%, and our forecast based on May 2011 data estimated 34.5%. Of the 86 polls published since January 2011, only 4 estimated PSOE at 28.7% or less, and only one of them is recent (a study by the Ortega y Gasset Foundation).
IU obtained 6.9% of the vote and 3.1% of MP's, a definitive improvement over 2008 and the party's best result since 1996. Extremely close to what the polls suggested. CiU got 4.2% of the vote and 4.6% of MP's (better than expected on the basis of polls) and UPyD got 4.7% of the vote and 5 MP's (also better than what the last polls suggested). Overall, then, PP did slightly worse, PSOE rather worse, and smaller parties better than expected.
In 2008, PP and PSOE captured 83% of the vote and and more then 90% of MP's. Yesterday, they got 73% of the vote and 85% of MP's. Turnout decreased, from 74% to 72%.
